You mean the AD-155C? I have one sitting on my desk for a project.

The BCMU360 is decent for small to medium sized sites. And it's
jumper selectable between 24 and 48 volts. There's an internal
DC-DC converter to take the 12VDC battery up to your selected
output. The charging is limited to 12W. I have a few with 30-40Ah
of battery connected. Recharge time is usually 12-14 hours. I had
a 95W site running on the 37Ah for almost 5 hours. It never went
down. Again, read the fine print. It's limited to 240W continuous
and 360W for 3.5 minutes. If it's in a not so temperature
controlled cabinet, don't even try to put more than 200-225 watts
of gear on it. I have a few sites running a couple ApexPlus radios
(75W a piece x 2) and other misc stuff, 450APs and a couple ePMP
PTPs. It's near the limit.
The regular BCM is a different story. There doesn't appear to be
any charge current limiting. I'm fairly sure I killed a TSP360. I
hooked up a string of 20Ah batteries to a BCM48 and it was pulling
10-12 amps out of the power supply. I could smell it starting to
cook. I gave up on it. I do only the BCMU360 and a Mean Well
SDR-240-48 now. Really small cheap-o sites get Mean Well AD-155's.
For anything over 200 watts, do yourself a favor now and look at
real rectifier solutions from Alpha, Eltek, Emerson or the new ICT
1U shelf which looks pretty good. That's where I'm going for the
sites that need more power and/or more run time. A good rectifier
shelf will have no problem with 100+ Ah of batteries and proper
maintenance of them, like equalization, etc.

I was simply referring to the time necessary to actually charge
the string of batteries.. in your case, it doesn't sound like
that is an issue (and it's not in my environment most of the time
either). I'm not sure if there are other problems with using a
large string like that on the BCM - but maybe someone more
knowledgeable like George or Ken can chime in?

Interesting....we have BCM48A and TSP-600 with 4x100ah.
We're not normally getting back to back power outages, so I
don't really care how long the charge time is.
How are we pushing it other than the recharge time? If we're
doing something wrong I really do want to know.

Yeah - I'm not sure the BCMU or BCM is the best solution for
that large of a battery string. If it did work (I guess it
probably would), it would likely take weeks to charge a
string of 4x100Ah batteries. You may want to take a look at
Eltek/Emerson or the new ICT shelf that was recently
announced on this list.
The largest string we have on the BCMU is 4x33Ah, and I have
even been told this is pushing it, especially with decent
charge times.

How large are your batteries? How large the load?

Hey guys I am completely new to Traco, so am feeling
my way through. It seems like power supply itself is
not relevant. But the BCM is. Someone suggested
using a TSP-BCM24 or TSP-BCM48 instead if I already
have 2 or 4 batteries in place,
What say you?

Not sure about the HRP. I've had SDR's running for
years now.

PSUI is who we order Traco stuff from. Do you
need 360W? The Mean Well SDR-240-48 is an
alternative. That's what I'm using with the
Traco BCMU360's. If you read the fine print,
it's worthless to put 360W behind the BCMU.
They're rated 240W continuous and 360W for 3.5
minutes. And the SDR-240 is ~$70 vs ~$270 for
the TSP360.
If you really need it, there's the SDR-480-48,
which is only 1/2 the price of a TSP360.
